Walter,
I made another observation regarding Default.
The beginning of the "Tx-only reserved parameters" section
on pg. 145 and the "Rx-only reserved parameters" section
on pg. 146 we have a general format description which looks
like this:
| (<parameter_name> (Usage <usage>)(Type <data_type>)
| (Format <data format>) (Default <values>)
| (Description <string>))
but later in the specific parameter discussions there is
not a single example using Default. Shouldn't the general
description of these two sections omit the Default, like
this:
| (<parameter_name> (Usage <usage>)(Type <data_type>)
| (Format <data format>) (Description <string>))
Thanks,
Arpad

Walter,
I want to ask a question about this BIRD.
My understanding of the Reserved parameters is that they
tell the EDA tool some information about the model. For
example,
| Init_Returns_Impulse, Use_Init_Output, GetWave_Exists,
| Max_Init_Aggressors and Ignore_Bits
are all parameters which provide information about what
the model contains or does, or conditions at which the
model should be operated at. Is the user of the tool and
the model expected to change the values of any of these
parameters? I don't expect that this would make sense...
In that case, why should we allow Default at all? I don't
see that there would ever be a choice to make with these
parameters. Shouldn't this BIRD simply replace the Default
with Value instead of allow both?
Thanks,
Arpad
